Abstract
A molecular phylogeny of the fungus gnat family Mycetophilidae based on the nuclear 18S, 28S, and the mitochondrial 16S rRNA genes is presented. The total alignment included 58 taxa and 1704 bp. The family was recovered as monophyletic in parsimony and Bayesian analyses. In the Bayesian analysis, Mycetophilinae and its two tribes, Mycetophilini and Exechiini, were monophyletic with good statistical support. The subfamily Mycomyinae was found consistently in a sister‐group relationship to Mycetophilinae. Gnoristinae was rendered paraphyletic, subtending Mycomyinae and Mycetophilinae. Within Gnoristinae, the genera Coelosia Winnertz, Boletina Staeger, Gnoriste Meigen group with Docosia Winnertz, usually considered to be a member of Leiinae. No support was found for the monophyly of the subfamilies Sciophilinae and Leiinae.
